Chapter 17: Q6. (page 483)

FIGURE EX17.6 shows a standing wave on a 2.0-m-long string that has been fixed at both ends and tightened until the wave speed is 40 m/s. What is the frequency?

Short Answer

Expert verified

40Hz

Step by step solution

01

Given Information

A wave is traveling with speed of 40m/s on a 2m long string fixed at both ends.

02

Concluding wavelength from figure.

Looking at the figure we can conclude that the wavelength (distance between two consecutive points in same phase in a wave) is 1m.

03

Substitute values in the formula

wavelength脳frequency=wavespeed鈬�1脳frequency=40m/sfrequency=40Hz

Hence, frequency of the given wave is 40Hz.

Two loudspeakers emit sound waves along the x-axis. A listener in front of both speakers hears a maximum sound intensity when speaker 2 is at the origin and speaker 1 is at x = 0.50 m. If speaker 1 is slowly moved forward, the sound intensity decreases and then increases, reaching another maximum when speaker 1 is at x = 0.90 m.

a. What is the frequency of the sound? Assume vsound = 340 m/s.

b. What is the phase difference between the speakers?

FIGURE EX17.15 shows a standing sound wave in an 80-cm-long tube. The tube is filled with an unknown gas. What is the speed of sound in this gas?

FIGURE Q17.8 is a snapshot graph of two plane waves passing

through a region of space. Each wave has a 2.0 mm amplitude

and the same wavelength. What is the net displacement of the

medium at points a, b, and c?

A sheet of glass is coated with a 500-nm-thick layer of oil 1n = 1.422.

a. For what visible wavelengths of light do the reflected waves interfere constructively?

b. For what visible wavelengths of light do the reflected waves interfere destructively?

c. What is the color of reflected light? What is the color of transmitted light?

Engineers are testing a new thin-film coating whose index of refraction is less than that of glass. They deposit a 560-nm-thick layer on glass, then shine lasers on it. A red laser with a wavelength of 640 nm has no reflection at all, but a violet laser with a wavelength of 400 nm has a maximum reflection. How the coating behaves at other wavelengths is unknown. What is the coating鈥檚 index of refraction?
